The Lenovo Storage Management Console is a web-based application for configuring, monitoring, and managing the Lenovo Storage S2200 or S3200 Series Storage Array. The SMC will be the starting point for the labs.

Some things to keep in mind as you use the SMC web-based interface (WBI):

• Do not use the browser's Back, Forward, Reload, or Refresh buttons. The SMC has a single page for which content changes as you perform tasks and automatically updates to show current data.

• In an action panel, an asterisk (*) identifies a required setting. • If an action panel has an Apply button and an OK button, click Apply to enable your

changes and keep the panel open or click OK to apply any changes and close the panel. After clicking Apply you can click Close to close the panel without losing changes already applied.

• To display context-sensitive help for the content of the topic pane, click the help icon in the banner.

The main areas of the interface are the banner, the topic tabs, the topic pane, and the footer, as represented by the following graphic:

__ 19. If any disks are being used as Global Spares (for example, disks 4 and 5), do the following:

__ a. Uncheck each disk that is being used as a global spare.

__ b. Click Change. The Processing the Request window is shown.

__ c. When finished, the Success window is shown.

__ d. Click OK to continue.



Lab Guide

At this point, you can start the lab with a Lenovo Storage S2200 and S3200 Arrays that is in a “clean” state.

Section 4. Creating a pool (Standard tier)

A pool is an aggregation of one or more disk groups that serves as a container for volumes. A disk group is a group of disks of the same type, using a specific RAID type that is incorporated as a component of a pool, which stores volume data. Volumes are added to a pool and the data is distributed across the pool's disk groups.

The system supports a maximum of 2 pools, 1 pool per controller module: A and B. You can add up to 16 virtual disk groups for each pool. If a pool does not exist, the system will automatically add it when creating the disk group. Once a pool and disk group exist, volumes can be added to the pool. Once you add a virtual disk group, you cannot modify it. If your organization's needs change, you can modify your storage amount by adding new virtual disk groups or deleting existing ones.

Depending on the type of disks selected and license installed, virtual disk groups belong to one of the following tiers:

• Performance Tier (SSDs): o Optional license is required for tiering with SSDs o No license is required for SSD Read Caching o No license is required for HDD tiering (no SSDs)

• Standard Tier (2.5” 15k and 10k SAS) • Achieve Tier (3.5” or 2.5” 7.2k SAS)

The Lenovo Storage manager automatically assigns drives to different storage tiers based on their speed. In this section, you create a pool by creating a Standard tier disk group consisting of several of the 10K SAS drives in the Lenovo Storage S2200 and S3200 Arrays.

Lab 2. Snapshots Estimated time

00:30


This lab is about creating, using, and understanding snapshots on the Lenovo Storage S2200 and S3200 Arrays.




• Create a snapshot of a LUN

• Remove host mappings to volume

• Restore a volume using a snapshot



Lab Guide

Lab instructions

Section 1. Creating Snapshots

Snapshots provide data protection by enabling you to create and save source volume data states at the point in time when the snapshot was created.

A base of 64 snapshots is included with all systems without an additional license. With a license, you can create additional snapshots. Multiple snapshots of a volume can be created including snapshots of snapshots.

The system treats a snapshot like any other volume. The snapshot can be mapped to hosts with read-only access, read-write access, or no access, depending on the purpose of the snapshot.

Snapshots use the rollback feature, which replaces the data of a source volume or snapshot with the data of a snapshot that was created from it.

In this section, you create a snapshot of a volume.



__ 2. From the Volumes list, select Volume 1.

__ 3. Click the Action button and select Create Snapshot. The Create Snapshots window is shown.

Figure 2 Create Snapshots window



Lab Guide

By default, a name corresponding to the volume will be used. In this case Volume 1_s0001.

__ 4. Keep this default snapshot name and click OK. The Processing the Request window is

shown.


Figure 3 Snapshot created successfully message

The snapshot has been created successfully. Now, if an accidental deletion happens, you will be able to restore the Volume 1 data to this point-in-time.

__ 6. Click OK to continue. The Volumes topic pane is redisplayed showing the new snapshot.

Verify snapshot creation

__ 7. Select, or leave selected, Volume 1.

__ 8. Click on Related Snapshots (if not already visible).

Each snapshot shows up as a new volume in the volume table with a type of snapshot.

__ 9. Select Volume 1_s0001 and click on Related Snapshots (if not already visible).

Figure 5 Volume 1_s0001 Related Snapshots information

__ 10. Verify that this snapshot belongs to Volume 1 by looking at the value shown in the Base Volume column.

Figure 6 Base Volume column value shows Volume 1

Section 2. Remove host mappings (prepare for rollback of volume)

In this section, we assume the following: someone has deleted some filesystem components and has corrupted the volume.

In this section, in preparation for the rollback of the volume using a snapshot, you remove all host mappings to the volume.

Before restoring a volume using a snapshot, both the volume and the snapshot must be un-mounted from the host. Note: The unmapping process is almost the same process as mapping, with the exception of choosing “Delete” as the action instead of “Map”.



Lab Guide

__ 11. From the Volumes topic pane, select Volume 1.

Lab 3. Multi-Tiered Pool and Tiering Demonstration Estimated time

01:00


Consider the following situation: a customer has limited budget, but needs high performance. Using Lenovo S Series Storage, you can use the real time tiering along with couple of SSDs to boost up performance while driving the total cost down.

This lab shows how by adding just a couple of SSDs and creating a Performance Tier in the pool the automatic tiering technology identifies the hot data and moves it up to the SSDs in real time.




• Add Performance tier

• Create a volume within the multi-tier pool

• Demonstrate / observe the Lenovo Storage S2200 and S3200 Arrays Real-Time Tiering benefits (using Iometer)



Lab Guide

Lab instructions

Section 1. Add a Performance tier

As mentioned earlier, depending on the type of disks selected and license installed, virtual disk groups belong to one of the following tiers:

• Performance Tier (SSDs): o Optional license is required for tiering with SSDs o No license is required for SSD Read Caching o No license is required for HDD tiering (no SSDs)

• Standard Tier (2.5” 15k and 10k SAS) • Achieve Tier (3.5” or 2.5” 7.2k SAS)

The Lenovo Storage manager automatically assigns drives to different storage tiers based on their speed. In this section, you create a Performance tier disk group consisting of several of the SAS SSD drives in the Lenovo Storage S2200 and S3200 Arrays.


Figure 1 Pools topic pane

Pool A should be shown as it was created in Lab 1. If Pool A is not shown, verify that Lab 1, Section 4 was completed successfully.
